On the Possibility to Observe h -> b-bbar with S/B ~ 1 in SUSY (mSUGRA), and Implications for Tracker and HCAL.

We study the possibility to observe the lightest SUSY scalar Higgs h in the mode h -> b-bbar in squark/gluino cascade decays in a tagged di-jet effective mass distribution in multijet + Et missing final state. The investigateion is done within the mSUGRA constrained MSSM model. We investigate...

description We study the possibility to observe the lightest SUSY scalar Higgs h in the mode h -> b-bbar in squark/gluino cascade decays in a tagged di-jet effective mass distribution in multijet + Et missing final state. The investigateion is done within the mSUGRA constrained MSSM model. We investigate the influence of the tagging efficiency, mistagging probability, geometrical coverage of the CMS microvertex detector and of the hadron calorimeter resolution on the visibility of the peak. We find that there is a very significant part of the mSUGRA parameter space where the h -> b-bbar peak can be observed with a signal to background ratio ~ 1. Within this model, the lower squark-gluino mass limit allowing the detection of the h is about 450 GeV, and observation should be pssible already with a few*10^3 pb-1, and extends up to quark - gluino masses of approx. 1.5 TeV with 10^5 pb-1. The a lmost entire h mass range from 80 GeV up to 125 GeV can be investigated this way.
